Folding Rigid Origami with Closure Constraints

Zhonghua Xi and Jyh-Ming Lien

Rigid origami is a class of origami whose entire surface remains rigid during folding except at crease lines. In this work, we developed a method using randomized search to find rigid foldable path for a given crease pattern with a goal configuration. A rigid-foldable path is defined as a path that has two properties 1. self-intersection free, 2. maximum edge deformation is under user given bound.
